Bird -Lore 



or of the Woodcock, which find their landing place in Jersey, is well 

 known to the peasants, who capture them by the thousand. 



It would be sufficient for the poor birds to baffle their enemies 

 only to change the route of their direction a few kilometers. But 

 they cannot do so ; they are fatally bound to the aerial way followed 

 in the preceding journey and cannot leave it without losing them- 

 selves. 



It is just so with other animals. Fish are cantoned. Certain of 

 them have, like the migratory birds, two or three domains that they 

 occupy successively. To go from one to another they emigrate in a 

 mass, and follow routes of which the traces are subject to the rules 

 we have set forth for the migration of birds. The relentless war 

 that fishermen with a knowledge of their habits make upon them 

 has never caused them to change their itinerary. 



Our theory of orientation seems, therefore, applicable to animals 

 of all kinds. It permits us to arrange and explain in a very satis- 

 factory manner a number of facts observed and known for a long 

 time.
